Toyota Citizen Wristwatch

This seems like a great idea: Toyota will introduce a Citizen Wristwatch with a smart key to lock and unlock cars automatically. The watch works with the new Toyota Crown car and transmits a radio signal a code to unlock the wearers car. The wristwatch will be available in Japan next week. We've seen a couple of car/watch combos before but not with this feature (how cool would this be with either Mercedes/IWC or Breitling/Bentley involved).
